Current-induced fragmentation of antiferromagnetic domains
M. S. Wörnle, P. Welter, Z. Kašpar +7
Electrical and optical pulsing allow for manipulating the order parameter and magnetoresistance of antiferromagnets, opening novel prospects for digital and analog data storage in…
Opportunities and challenges for spintronics in the microelectronic industry
Bernard Dieny, Ioan Lucian Prejbeanu, Kevin Garello +22
Spin-based electronics has evolved into a major field of research that broadly encompasses different classes of materials, magnetic systems, and devices. This review describes rece…
Single-atom electron paramagnetic resonance in a scanning tunneling microscope driven by a radiofrequency antenna at 4 K
T. S. Seifert, S. Kovarik, C. Nistor +3
Combining electron paramagnetic resonance (EPR) with scanning tunneling microscopy (STM) enables detailed insight into the interactions and magnetic properties of single atoms on s…
Chiral anisotropic magnetoresistance of ferromagnetic helices
Henrik Maurenbrecher, Johannes Mendil, George Chatzipirpiridis +4
We investigate the anisotropic magnetoresistance (AMR) of ferromagnetic CoNi microhelices fabricated by electrodeposition and laser printing. We find that the geometry of the three…
Current-induced switching of YIG/Pt bilayers with in-plane magnetization due to Oersted fields
Johannes Mendil, Morgan Trassin, Quingquing Bu +2
We report on the switching of the in-plane magnetization of thin yttrium iron garnet (YIG)/Pt bilayers induced by an electrical current. The switching is either field-induced and a…
X-ray spectroscopy of current-induced spin-orbit torques and spin accumulation in Pt/3d transition metal bilayers
C. Stamm, C. Murer, Y. Acremann +10
An electric current flowing in Pt, a material with strong spin-orbit coupling, leads to spins accumulating at the interfaces by virtue of the spin Hall effect and interfacial charg…
